Abstract

A pressure sensor for an internal combustion engine has a piezoceramic transducer in an operating connection, by way of a plunger, with a membrane, the sensor being secured in a cylinder head of an internal combustion engine with the membrane located within a cylinder. The pressure sensor serves for detecting knock and ping.
